Description Cor Nouws 2013-07-02 22:05:14 UTC
Hi,
Just data dump:
Vanilla LibreOffice, cold start on Ubuntu, 366: 7sec; 404 9 sec; 410rc1 15 sec
Maybe just the rc1, or calculated because of the implementation of ??
Second start is fast, but also appr. twice as much: 2. .. / 2. .. / 4. ..
(Numbers Windos users prolly can only dream of ;) )
Comment 1 Michael Meeks 2013-07-03 18:51:08 UTC
Interesting; if you do:

export OOO_EXIT_POST_STARTUP=1
export OOO_DISABLE_RECOVERY=1

and run:

time ./soffice.bin -writer

a few times - what times do you get ? I see a small slow-down for 4.1 (which we need to fix), but it's not 2x:

1.642s for 4.1
1.335s for 4.0

over several runs. That's not ideal though, so I'll build a profile :-) Perf. regressions are also somewhat embarassing => mab4.1

Hi Michael,
It's this:

(all 410rc1 - 40x interesting too? )
Comment 4 Michael Meeks 2013-07-05 15:47:14 UTC
Sure - vital to compare on the same machine of course :-) I've pushed a few patches that get my time down to 1.580 or so; one of the biggest chunks of time is spend on fooling around with parsing and handling fonts that we don't care much about: AFMs - which is annoying.
Comment 5 Michael Meeks 2013-07-05 15:53:53 UTC
Oh - another -critical- thing to get right is that you must compare apples with apples; comparing the stock / distributed package of LibreOffice with a downloaded version is 100% unfair, and will inevitably be a lot slower: not using system libraries, not using --merge-libs etc. etc. are you comparing 2x download/installs of 4.0.x and 4.1.x ? you said Vanilla but ... ;-)

Good question, but I've all the approximately 110 versions in parallel installation ;)

caolanm->cor: output of fc-list |wc -l ?, i.e. how many fonts do you have. If you've a lot then I reckon http://cgit.freedesktop.org/libreoffice/core/commit/?id=019a8f3f74ec778d5fead4d2b4d47e75cf750bf7 will make a major difference.

Comment 20 Michael Meeks 2013-07-12 08:51:21 UTC
With Caolan's fix (and mine - which will not make it to -4-1-0 but only -4-1-1) I get from:

1.642s for 4.1.0rc1
1.460s for 4.1.1
vs.

1.335s for 4.0

So - nearly 'fixed' :-) I'll run a new callgrind trace to see what's else looks unexpected; clearly we badly need those perf. regression tests that Matus created running regularly.
Comment 21 Michael Meeks 2013-07-12 09:02:30 UTC
Doh; my numbers were messed up by having the logo toolbar visible; disabling that helps a lot; now back to:

1.380s for 4.1.1
vs.
1.335 for 4.0.0

The difference starts to approach measurement accuracy; will callgrind the right thing now ;-)
Comment 22 Michael Meeks 2013-07-12 09:20:35 UTC
Nothing else that is really obvious jumps out at me; though the framework / configmgr / vcl interaction around the construction of toolbars / frames around windows is 'orribly expensive I estimate ~25% of the time creating a handful of toolbars, and menus; which can't make sense.

Still I'm impressed (would love to have more time to spend in technical stuff ;) ) 
. Thanks!
